MyBB Community Forums

Hello! Use of reverse proxy (I do not use cloudflare) mybb 1.8, but there is a problem. Design is partially lost. When refresh appears then disappears again. When a new topic is not loaded bb codes and emoticons on the left.
And if you load very slowly. What caused this problem with the loss of design and how to fix it?

I changed the web host and problem will be fixed.
#Please, closed topic
Thanks
